CAP FOR STEAM-PIPE CLOTHING.

SPECIFICATION forming part of Letters Patent No. 276,044, dated April17, 1883.

Application filed March 8, 1883. (No model.)

To all whom it may concern.-

Be it known that I, PETER HOLT, a citizen of the United States, andresiding in Philadelphia, Pennsylvania, have invented a certain Cap forSteam-Pipe Clothing, of which the following is a specification.

My invention consists of a device, fully described hereinafter, forpreventing the disintegration of the ends of the non-c0nducting clothingwith which steam or hot-air pipes are often covered.

In the accompanying drawings, Figure 1 is a longitudinal section of apipe, its non-cond nctingclothing, and annular cap for the same; Fig. 2,an end view of the cap, and Fig. 3 a perspective view of the same.

The non-conducting clothing B of the pipe A consists in the presentinstance of an inner layer, a, of asbestus board or composition, anouter layer, (6, which may be of the same material, and an intermediatelayer, 1), of felt or hair. My invention, however, is not restricted toany specific kind of clothing, for all modern pipe-wrappings are apt tobecome disintegrated atthe points Where they are necessarily cut awayfor exposing the pipe wherever it is necessary to make attachmentsthereto. In order to prevent this I use an annular cap, D, made in twoexactly similar parts, as best observed in the perspective view, Fig. 3,each part consisting of a semi -annular piece, 61, adapted to fit on theoutside of the non-conducting clothing, a smaller semi-annular piece, 6,to fit to the pipe, and the beveled connecting-piece f, the whole beingpreferably composed of sheet or cast metal, and provided with lugs t' z,for receiving bolts by which the two parts are secured together, so asto inclose the clothing of the pipe at and near the end of the same. Theintermediate beveled piece of one or both parts of the cap is of such alength that the beveled piece of one will overlap that of the other,thereby preventing all exposure of the end of the clothing, which beingthus contained within the cap is not liable to be disintegrated.

I claim as my invention 1. The combination of a pipe and pipe-clothingwith a cap, D, made in two parts for embracing both clothing and pipe,substantially as set forth.

2. The within-described cap for pipe-clothing, the same consisting oftwo parts, each composed of the semi-annular pieces d and e andconnecting-piecef, and each part provided with lugs 27, allsubstantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER HOLT.
